Learn from others’ past mistakes.
· Never, ever, leave a chuck key in a chuck.
· Lathes - and especially some milling machines - are very top heavy. Take care when moving them round the workshop, and don't do it alone.
· Moving a machine? Take off rings and other jewelry. A friend was pulled over and his hand badly mangled by a toppling machine when the sharp edge of a tool-post bolt caught his wedding ring.
· Keep a clear, safe and oil-free working area around your machine tools. You must be able to think of better things to do than tripping, slipping or falling onto a rotating cutter or mechanism.
· Wear snug-fitting, tightly woven clothes and remove anything that might get wound into rotating mechanisms.
· Wear eye protection.
· If you don’t how it works, read the instruction manual.
· After setting up any turning job, take a moment to pull the job round by hand to check that everything clears.
· Remember, you are using a machine tool - an expensive, precision device. Keep it clean and oiled - and don't abuse it.
· Keep the machine and area clean.
· Lubricate plain headstock bearings with light oil - little and frequently. Adjustable-drip oil pots (as fitted to Myford ML7 lathes, etc.) may look old-fashioned, but you can see exactly what is happening - and they are completely effective.
· If your lathe headstock has an oil supply held in reservoirs under the bearings, with wick or other feed - check the level every day.
· Small lathes need all the help they can get. The secret of successful operation is to keep the cutting tools sharp by using a slip stone across the top surface; the sides rarely need attention.
Turned Chess Pieces
When taking a cut with one slide, for the best finish, lock the others (top slide, cross slide and carriage).
Use a 4-jaw chuck to grip irregular or roughly finished material - using your 3-jaw like a bench vice will ruin it.
Before inserting a center in either the headstock or tailstock, clean out the taper carefully (and center) first.
The headstock center is soft and the tailstock center is hard – but there is no harm in using a hard center in either.
The soft headstock center can be trued-up by being turned in position with the top slide; when this has been done make a small corresponding mark on both the center and spindle nose so they can always be put back together in the same position.
Do not mesh change wheels tightly; some clearance between them is necessary.
On small lathes parting-off operations are likely to cause the greatest trouble.
When truing up a lathe faceplate, place your centers in the headstock and tailstock spindles.
